To all 'whom' it may concern-.-v

Be it known hat: we, JULIANv J MOMBE- TRY and vEAR'ILV. MGMURTRY, citizens of the United States, residents of theV city and county of San F rancisco and State ofCalifornia, have jointly invented a new .and

useful Improvement in APaper-Boxv-'la'ping Machines, of which the'4 following is a speci'- cation.

Our invention relates to improvements in paper box taping' machines wherein duplicate tapin mechanisms operate in conjunc- 'tion with improved'ineans' foradjusting thef distance between said duplicate mechanisms'` to insert and'secuie the ends of separate tapes or the endso'f a single tape through av paper box blank attwo separate' points; and the objects'of ou` invention are' First, to provide anV improved device adapted to secure the ends of ai' tape or tapes space orV distance between the' duplicate taping mechanisms to accommodate saidv dis'- tance'to the length'of a single tape toy be usedY for a handle) or carrying means, or for.' two separate tapes wherebyvarious sizes of blanks may be taped'.

7e 'accomplish these several' objects by means of the device' 'disclosed in the drawings forming'a-'part of the present"specifi#y cation whereinV like characters ofl reference are used to .designate'similar parts througli out the said vspecification and drawings, and in which;

32 which extends Vupwardly andinfrntof the plate 2 to a point opposite the container 16 in the back of said plate 3.

Slidably mounted Awithin the upper end of the standard 32 is a taping needle 33 of the usual type having an inclined slot 34 in the end thereof. foot 37 is also slidably mounted in the upper portion of the standard 32 and immediately below the needle 33. The stem 36 of the presser foot 37 is provided with a rigid collar 38 and a loose collar 41 and a spring 39 is interposed between the two collars.

A bell crank lever 42 is pivotally mounted as at 43 to the standard 32 and is operatively connected, by means of' a link or connecting rod 44, to an operating rod 46 slidably mounted within suitable bearings 47 of the standard The lower endo-t' the rod 46 is provided with a roller 48 which is engaged by a cam 49 on the sleeve 26 feathered to the power or driving shaft 27.

A spring 51 is interposed between a rigid collar 52 on thel rod 46 and the upper bearing 47 for said rod and operates to retain contact between the.' roller 48 and the cam 49' on the sleeve 26.

Each sleeve 26 is further provided with ay bevel gear v53 meshing with a second bevel gear 54 on the counter shaft 56 rotatably mounted within each unit or subframe 14. The other end of each counter shaft 56 is also provided with a bevel gear 57 which meshes with a bevel gear on the lower end of a vertically disposed shaft 59 having its upper end rotatably held in a suit-able bearing 61 on each adhesive container 16.

The top of each shaft 59 is providedwith an arm 62 having a roller 63 thereon to engage and move a lever 64 pivotally mounted Within a suitable bearing 66. The free end of each lever 64 is operatively connected to a parallel bell crank 67 pivotally mounted as 'at 68 within a slide 69 mounted within guide ways 71 formed on the adhesive container 16, Y p

The parallel bell crank levers 67 arejp'rovided with a roller 73 adapted lto be moved or rolled within the slot 3 of the plate 2 and against the back of the paper boX blank 7 to press thefprojected ends of the tape, not shown, onto thepreviously applied adhesive when. the lever 64 is moved in oneV direction and to be held away'from said paper box blank 7 in the return direction.

'The operation is as follows:

The blank paper box, in a knock down condition, is placed on the supports 6" slidably mounted within the vertical slots 4 of the plate 2so that the `points through which the tapes are to be inserted lie directly over the horizontal slot 3. n

. The subtrames 14 are moved toward or away from each other to bring the tapering needles 33 opposite the points where the tape is to be inserted by rotating the threaded A stem 36 of a presser parallel rods 9 by means of the handle 7 3 attachedY to one of the rods, or by any other suitable means.

As the rods are connected by the chain12 and sprockets 11 it is obvious that when both rods are rotated the subframes 14 will be moved, by means of the oppositely threaded ends of said rods 9, either toward or away from each other according to the direction of rotation of'lsaid rods and the threads thereon. y

lVhen the needles 33 have been properly alined the rotation of the power shaft 27 will rotate the sleeves 26, which are feathered to said power shafts 27, and cause the cams 24 to engage the rollers 23 and operate the levers 21 to move therollersv31 up the inclined adhesive spreaders or disturbers 17 and into the slot 3 and against theV back of the paper boX blank 7 thereby depositing adhesive on the back of said blank at the points adjacent to where the tape is to be inserted. As the cam releases the roller 23 a spring 76 secured to each lever 21 and each subfraine 14, returns said levers and rollers 31 to their respective containers 16.

A' continued rotation oit' the power shaft 27 will cause the sleeves 26 to bring the cams` 49 into operative relation with the rollers 48 on the rods 46 thereby operating the needles 33 to carry tape ends through the paper boX blank 7, and through the slot at points adjacent the applied adhesives.

The relative position of the'needle 33 to the adhesive applying rollers 31 is disclosed in Fig. 5 of the drawings.

As the needle 33 advaneestoward the blank 7 the stem 36 ofthe presser foot ,37 is engaged by the bell crank lever 42. As they presser foot 37 is positioned in advance lof the needle 33 it is evident that said presser foot will first engage the blank 7 and the continued movement of the lever 42 will be permittedby the compression of the spring 39, said spring operating to'retain the blan r 7 against the plate 2' until Ythe/needle 33 is withdrawn therefrom aftergha'ving passed the tape end through said blank 7.

The cams 49 are adapted to permit a quick return of the needles 33 so that the friction of the card board blank'7 will stripthe tape ends from theslots 34 ofthe needles 33, each presser foot '37 operating toreta'in the blanky 7 against the plate 2 luntil the needles have been withdrawn.l V Y The continued rotation of the power shaft 27' willvrotate the gears'f64, 57 and 58and the rods 59 to cause thearms 62 and rollers 63 thereon to engagethe levers 65 andtoV move said levers vtoward the adhesive container 16. 'f

As thelevers 64 move forward the action or movement thus transmitted tothe bell then along said blank to engage the inserted ends of the tapes and press said ends against the previously applied adhesives.

The return movement of the lever 64, which is facilitated by the coil spring 77 first operates the bell crank levers 67 to move the rollers 7 3 away from the applied tape ends on the back of the blank 7, until tlie shorter ends or armsof said levers 67 engage the stops 79 on the backs ofthe slides 68 when the continued movement of the lever 6l will return the slides 69 to normal position as disclosed in Fig. 5 of the drawings.

The blank 7 is then removed and another blank inserted in its place and the above described process is repeated. Y

It is obvious fromthe foregoing that we have provided an improved machine adapted to secure tape ends to paper box blanks as well as improv-ed means for adjusting the distance between the points where said tapes are-to be secured. Y

Having thus described our invention what we claimas new and desire to secure by Let l. A taping machine comprising a suitable frame; adjustable mea-iis secured to the frame to retain a paper box blank to be taped; means for applying adhesive at two points on the blank; means for inserting the Y ends of two separate'tapes through the blank adjacent the applied adhesives; and means for pressing the ends of the tapes onto their respective adhesives; and means for varying the space betweentlie adhesive, tape inserting and tape pressing means.
